Manning liquidated his stake two days before the National Football League severed ties with Schnatter's billion-dollar business. In late February, the NFL dropped Papa John's as its official pizza sponsor and switched to Pizza Hut.

Manning didn't respond to the Denver Post's request for comment and remains Schnatter's pizza ambassador, but it seems unlikely they'll be sharing any more corporate box suites.

Schnatter's NFL trouble has been ongoing. Last December he stepped down as CEO in the wake of controversial remarks that NFL anthem protests had caused poor pizza sales.
